Abstract
|
|
|
|
I studied about temperature and pH concentration having influence upon chlorophyll decrease on the Glucose culture of Chlorella variegata Beijerinck(211/10a). I cultured under 25℃(standard), 15℃ and 35℃ and compared with each other. The culture of 15℃ didn’t have any large difference with the standard culture(25℃) but the culture of 35℃ had a large amount of chlorophyll decrease without carbohydrate accumulation, stimulation of cell division and nitrogen-deficiency. Chlorella variegata had optimum pH 6.5-7 and was a little weak in all phenomenon under pH 8 rather than under pH 6.5-7. Under pH 5 they had deep chlorophyll decrease without pheophytin.
